Regional Disparities in Brazilian Adult Mortality: an analysis using Modal Age at Death (M) and Compression of Mortality (IQR)

Abstract

This paper examines mortality differentials in Brazil and states between 1980 and 2010,using the Brazilian Ministry of Health Database. We use Modal age at death and measures of mortality compression to analyze regional and gender differences. We estimate age-specific mortality rates by single ages using two approaches: Wilmoth and colleagues (2012) Log-Quad approaches and Topal´s method proposed by Gonzaga and Schmertmann (2016). Our results show that provincial disparities in mortality in general across regions of the country. Moreover, based on the modal age at death and the interquartile range (IQR) of ages at death. We find that there is a process of compression of mortality with increasing modal age at death.

Estimation and projection of probabilistic age- and sex-specific mortality rates across Brazilian municipalities between 2010 and 2030

“…The trend towards a rectangular survival curve was more pronounced among women than men. As observed in other countries, the projections also suggest a continued decline in mortality among older age groups and an increase in the modal age at death [63,64]. The observed decline in mortality, which is a key driver for gains in life expectancy at all ages, may be partly attributed to improvements in the Brazilian population's living conditions [55].…”

Mortality modeling at old-age: a mixture model approach

“…In general terms, the debate is whether mortality at older ages is declining or continues to increase (Gavrilov & Gavrilova, 2019;Feehan, 2018). In some settings, such as Brazil, there is also an important question on the crossover of mortality at older ages when comparing different population sub-groups (Nepomuceno et al, 2019;Pinheiro & Queiroz, 2019;Gomes & Turra, 2009).…”
